Over the past week, Ozon has strengthened the operational contour for sellers — through a contract, warehouse scenarios and issue analytics. Such changes rarely sound loud, but they are the ones that shape the bottom line in terms of margin and risk.
The changes in the contract (from March 18, 2026) are primarily the rules of the marketplace's actions in the warehouse and in logistics. In controversial situations involving prohibited goods, documents, disposal and processing, it is the contract that determines what the site does and what consequences remain with the seller. For a business, this is a direct financial risk: an error in the assortment or documents may not cost a fine “on paper”, but the inability to return the goods, the loss of a batch, or the cost of correcting the situation.
The practical conclusion here is simple: contractual updates should be read as a risk guide. For at least a week after the change, you should do three things: check the assortment for restrictions, update the checklist for the warehouse/fulfillment, and appoint a responsible person who monitors contractual changes. This is not marketing, this is OS security.
Repackaging and logistics are a separate area that hits the cost. If part of the operations is transferred to the marketplace warehouse and the cost of processing changes, the seller's SKU math changes.: which is more profitable — to repackage yourself or lay the processing on the warehouse side. It is important that repackaging often “pops up” not as a separate article in your head, but as a series of deductions and changes in reporting. Therefore, it should not be left unchecked.
What should be done: identify the categories and products that are more likely to be repackaged, look at the reflection in reporting and deductions, then recalculate the economics of key SKUs, taking into account the actual cost of operations. This helps to avoid the classic situation: sales are there, turnover is growing, and profits are disappearing imperceptibly.
Ozon has improved the "What affects the place in search" tool by adding more promotion data in the pay-per-click and pay-per-order models. The practical value here is in the diagnosis: the seller understands more quickly why the card falls in the issue, and can distinguish between two reasons — the “card problem“ and the ”advertising problem". This speeds up decisions: where to refine the content, where to change the price/ availability, and where to adjust the campaign.
A working scenario for the week: select 5-10 key cards, look at the factors that are pulling the position down, plan changes for one or two factors (not all at once), then record the result for conversions and sales.
Additionally, product collections and merchandising are mentioned in the week's updates. For those who use collections as a sales tool, the changes are important because they affect the manageability of the showcase and the budget if some of the functions are linked to subscriptions or access levels. The rule is the same here: evaluate a function through economics — whether it provides an increase in turnover and margin that covers the cost of access and the time of the team.
The outcome of the week for Ozon can be formulated as “three points of control.” A contract is a risk regulation. Repackaging is the cost. A search is a diagnosis of the causes of a drawdown. If you keep these three zones in order, the seller is less dependent on surprises and returns profit control faster.
